Abstract
In the course of our research for the low-molecular weight RGD peptide mimi
cs, we have found that a rigid 2-acylimino-3H-thiazoline structure is suita
ble for the peptide backbone mimics. Introduction of amidinophenyl and p-al
anine moiety as arginine and aspartic acid side-chain surrogates to this ba
ckbone mimic resulted in a highly potent fibrinogen receptor antagonist 2-(
4-amidinobenzoylimino)-3.4-dimethyl-N-(2-carboxyethyl)-3H-thiazoline-5-carb
oxamide (7c). namely PS-028 (K-i, = 46.5 +/- 5.5 pM). (C) 2001 Elsevier Sci
